Our kids are constantly cooking these things. Some like them just with cheese, others like to add ham, pickles, and mustard.
Casadilla (like how they spell it?)
Turn knob to 6. Put dough on pan. Wait until little bubbles, then flip it over, add cheese. Wait until the edges are melted, then turn knob to 6, and put ham on. Wait like 10 seconds, take dough off pan onto wood (we have a wood cutting board). Then add mustard and pickles, if needed. :)
